Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In rat brain, the body's own DSIP-like immunoreactivity was visualized in structures of the indusium griseum, septum, hippocampus, pallidum, hypothalamus, hypophysis and neocortex.

    In plain wordsIn rats, the body's own DSIP-like material was seen in many brain areas, including the hippocampus and hypothalamus.

    Summary
    Two indirect immunohistological methods (PAP and immunofluorescence) allowed them to visualize, for the first time, structures containing specific DSIP-like immunoreactivity in some areas of the rat brain: indusium griseum, nucleus septi lateralis, hippocampus, striae longitudinales of Lancisi , ban…

    Summary · context
    In their work, the authors used an anti-DSIP antiserum suitable for immunohistological purposes.

    This result measures the body's own Delta sleep-inducing peptide (DSIP). Nobody was given the peptide. It is not evidence about taking it.

Studies that did not test the peptide alone1

In this study, Delta sleep-inducing peptide (DSIP) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Delta sleep-inducing peptide (DSIP).

    The authors developed a method to visualize DSIP in histological preparations under light and fluorescence microscopy.

    In plain wordsIn rat brain tissue, researchers developed a way to see DSIP under a microscope.

    Summary
    The authors have developed a method which makes it possible, for the first time, to visualize the delta sleep-inducing peptide in histological preparations and study it under the light and fluorescence microscope.

    In this study, Delta sleep-inducing peptide (DSIP) was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Delta sleep-inducing peptide (DSIP).
